double SigmaPrime( double x, double t ) |
Parameters
- x
- Type: System..::.Double
A double, the point in space at which is to be evaluated.
- t
- Type: System..::.Double
A double, the time point at which is to be evaluated.
Return Value
A double, the value of at (x,t).Remarks
Time dependency of can be controlled via method
SetTimeDependence. Use of this method will usually yield a more efficient
algorithm because some finite element matrices do not have to be reassembled for each
t value.
